    During aerobic respiration, acetyl Co-A is synthesized in

    A)  cytosol

    B)  mitochondrial matrix.

    C)  glyoxysomal matrix

    D)                  perichondrial space

    Correct Answer: B

    Solution :

                    Pyruvate a final product of glycolysis is formed by the glycolytic catabolism of carbohydrates in the cytospl. After it enters mitochondrial matrix and undergoes oxidative decarboxylation by a complex set of reactions catalysed by purify dehydrogenase. Pyruvic acid + Co - A + \[NA{{D}^{+}}\]\[\xrightarrow[Pyruvate\text{ }dehydrogenase]{M{{g}^{2+}}}Acetyl\,Co-A+C{{O}_{2}}\]\[+NaDH+{{H}^{+}}\] Acetyl Co-A is a connecting link between glycolysis and Krebs cycle.
